Supplementary data for paper: Soil Physical Characteristics and Saturated Hydraulic Conductivity in the Landform of Barito Delta, Kalimantan, Indonesia

This data contain soil textures, bulk density, soil organic matter, saturated hydraulic conductivity, landform map, soil sample location map, electrical ressistivity measurement location, and soil profile location. Soil samples are taken in each depth of soil until 5 m depth. The sample is taken representatively in every landforms in Barito Delta. Soil sample is not taken until 5 m depth in case it found fine sand material. It is because this sand material is from ancient sedimentation that occured in the past. The sample is not taken in Oxbow Lake because it is mostly covered with grass land and water. Particle size distribution (% clay, % silt and % silt) is defined from laboratory testing. USDA triangle texture is used to determine soil texture. Bulk density is sampled in land surface only or at 1 meter depth since the value is almost homogenous in peatland. Soil organic matter (SOM) is sampled similar way with soil texture. Soil profile location is used to characterize soil texture in each depth of each landform in Barito Delta. Bayesian statistics is used to interpolate soil fraction in each depth to derive soil fraction map in each soil profile location. Saturated hydraulic conductivity is estimated from every sample and every depth applying Saxton and Raws (1986) and (2006), Weynants et al (2009) formulas. Research objective is to characterize soil fraction, soil texture, soil organic matter, and saturated hydraulic conductivity in peatland of Barito delta where get influence from river and sea sedimentation. Soil sample for soil texture, soil organic matter, bulk density and electrical resistivity measurement are primary data. Landform is mapped using fieldcheck in 2011 of land use from landsat year 2008; soil map from institution scale 1:250,000; and topography map scale 1: 250,000

本数据集涵盖土壤质地（soil texture）、容重（bulk density）、土壤有机质（soil organic matter, SOM）、饱和导水率（saturated hydraulic conductivity）、地貌图、土壤样点分布图、电阻率（electrical resistivity）测量点位以及土壤剖面点位。
土壤采样按土层深度逐层采集，直至5米深度。采样点位在巴里托三角洲（Barito Delta）的各类地貌中均具有代表性地布设。若在采样过程中发现细砂物质，则停止向下采集至5米深度，因该砂质物质为远古沉积成因。牛轭湖（Oxbow Lake）区域不布设采样点，因该区域多被草地与水体覆盖。
粒度分布（黏粒百分比、粉粒百分比及粉粒百分比，原文存在重复表述）通过实验室测试确定。采用美国农业部（USDA）质地三角图法确定土壤质地。鉴于泥炭地内容重值近乎均一，故仅在地表或1米深度处采集容重样品。土壤有机质（SOM）的采样方式与土壤质地相同。
土壤剖面点位用于表征巴里托三角洲（Barito Delta）各类地貌各土层深度的土壤质地特征。采用贝叶斯统计方法对各土层深度的土壤组分进行插值，以生成各土壤剖面点位的土壤组分分布图。
饱和导水率通过各采样点各土层的样品，采用Saxton与Raws（1986、2006）以及Weynants等（2009）提出的公式估算得到。
本研究的目标是表征受河流与海洋沉积作用影响的巴里托三角洲（Barito Delta）泥炭地内的土壤组分、土壤质地、土壤有机质及饱和导水率特征。
用于土壤质地、土壤有机质、容重及电阻率测量的土壤样品为一手实测数据。
地貌图基于2011年野外核查获取的2008年陆地卫星（Landsat）土地利用数据、比例尺1:250000的机构级土壤图，以及比例尺1:250000的地形图编制而成。
